External Crank Trigger?

[rjblaze]

Just checking in to see if there has been any progress.

I have spent time trying to find a solution but have made no progress. GM made different versions of the RWD dampener and pulley setups. Some use three bolts and others use four bolts to mount the crank pulley. I need measurements for the distance from the face of the block to the rear edge of the belt and from the block to the face of the dampener on various vehicles so I can determine if a universal trigger setup can be made.

Just wondered on progress for a RWD-type trigger wheel yet? Would it be possible to machine the face of a RWD damper "flat" and sandwich your trigger wheel between the modified damper and pulley?

No progress due to limited time and not having any RWD vehicles to work with. I do know someone who recently picked up a Fiero with a 2.8 but schedules haven't permitted me to get measurements. He with be moving close to me in the next few weeks and I will have easy access to it for measuring.

My plan is to modify the stock dampener and bolt the trigger wheel to it. A problem is that some dampeners have 4 spokes while others have 3 spokes. The spoked area has the most mass and would be the best place to add bolts. I also need to see if any components from our FWD trigger mount will work with that setup or if a complete new system has to be made.

Great! Just checking...thanks for the update. I really hope you find a solution.

I can pretty much tell you that the Fiero's have 4 bolts holding the pulley to the damper.

Any luck yet?

I guess no progress as of yet?

[rjblaze]

Figured I would check back to see if there was any progress towards an external trigger for RWD-type dampers like on my Fiero

Just nchecking back for progress updates on the RWD-type trigger. Any luck yet?

what size is the bolt that holds the crank trigger sensor into the housing?
it looks like its a 5mm, but i only had a 5x1.0thread in stock, doesnt seem to fit correctly, dont want to strip it.

[CNCguy]

It's a UNC #10-32 thread.

Edit: PM me your address and I will drop one in the mail to you at no charge.
